WIRE- STRETCHER.

Specification of Letters Patent. Patented Aug, 19, 1919,

Application filed April 10, 1919. Serial No. 288,960.

To all whom it may concern:

Be it known that I, FRANK W. SCHU- MAC/HER, a citizen of the UnitedStates, residing at Shawano, in the county of Sha- Wano and. State ofl/Visconsimhaveinvented certain new and useful Improvements in Wire-Stretchers, of which the following is a specification. I

, This invention relates "to; pushing and pulling implements, and moreespecially to stretchers operating on the step. by step principle; andone object of the same is to produce an improved fence-wire stretcherwhich is capable of use between posts Within the run of the fence, orbeyond the endmost post when the operator reaches the-end of said run.

'Another object-is to produce a structure which grips thewire at twopoints, one on either side of the post, so that the wire can be stapledto the post after it is stretched.

Another object is to provide a detachable shoe which is not applied whenstretching is done between posts.

Other objects will appear in the following specification and claims.

In the drawings Figure 1 is a plan view of this wire stretcher with itsparts assembled as when it is attached to the end'post, and

Fig. 2 is a side elevation thereof.

Fig. 3 is an enlarged plan View of the movable slide and pawls.

Inthe drawings the numeral 1 designates the ordinary bar havingstaggered notches 2 in its sides and herein shown as provided at one endwith a hook 2 which may be at tached to a post and a chain 3 with a grip3 to be attached to-the wire when the wire is to be stretched within therun of the fence. The other end of the bar 1 is proyided with a tongue 4adapted to be slipped into a socket 5 which carries a shoe 6 pref-'erably having points 7 whereby it may rest against a post P when thewire W is to be stretched at the end of a run of fence, or in otherwords when the stretcher is to be employed beyond the line of the fenceitself. In this case, the chain 3 cannot be attached to the fence postbecause there is no such post, and it may well be led over along thedotted line of Fig. 2 and attached to the upper end of the post P tohold the notched bar 1 horizontal. The shoe 6 may be attached to thepostP in any suitable manner, as by a clamping chain 8 carried around. the

same and engaged with azh-ook 9 onthe shoe.

It isv to be understood that this shoe and socket are not employed whenthe stretcher is used within the length of the fence.

. Slidably mounted on then'otched bar is, a hollow member or slide 10bestseen in Fig. and pivoted at 11 across the same is a lever 12 towhich at 13 are pivoted pawlsla whose active ends-are. thrown normallyinward by springslo engaging the sides, of the slide as seen in Fig. 1Therefore, when the lever is recipro'cated, the .pawls cause the slideto: travel to the. left along. the notched bar in a manner which willbev clear.

A pulley 22 is pivoted on the slide 10 as at 21, and the pins 11 andv,21 connected by asides of the post P, the grip 2-1 being considerablynearer the stretching mechanism than the grip 25. In other words, thelastnamed grip is within the line of the fencing, while the grip 24 isbeyond the post P which is here the left postof said line. The chain 23which connects the grips passes the post from the grip 25 and runsfreely around the pulley 22, but it is quite possible to provide meansfor preventing the rotation of said "pulley when desired. The grip 24carries a hook 26 and the chain 23 has a large link 27 adjacent the grip25.

When this stretcher is used within the line of the fence, thehook 2 isattached to a post and the grips 24 and 25 to a wire to be stretched, orthe grip 25 can be attached to the wire and the hook 26 on the grip 24maybe engaged with the large'link 27 onthe grip 2 5. Then bymanipulatingthe lever, the slide 10 is caused'to move to the left andthe wire is stretched as clearly understood. hen this device is to beused at the end of a stretch of fence, the shoe 6 is brought into useand the socket 5 is slipped over the tongue 4 at the right end of thenotched 12 is reciprocated, the pawlscause it to travel to the leftalong the notchedbar and the pulley 22 strains both stretches of thechain 23. The result is that the grip 25 draws on the main portion ofthe wire W while the grip 24L draws on that portion of the wire betweenthetwo grips, whichp'or tion extends alongsidethe post, and. there forethe wire may be stapled thereto before tension on the structure isrelaxed. Now a reversal of the operation removes the stretcher and it ispossible to reset it at a lower point on the post so as to stretchthewire WV below; The parts are by preference entirely of metal, andchanges in detail may be made as come Within the scope of the invention.

The foregoing description and the drawings have reference to what-may beconsidered the preferred, or-approved form of my invention. vIt is to beunderstood that I may make such changes in construction and arrangementand combination of-parts, materials, dimensions, et cetera, as may proveexpedient and fall within the scope of the appended claims.

l/Vhat isclaimed as new is:

1. Ina fence wire stretcher, the combination with a" bar, a slidemovably moimted thereon, means for causing its progression alongthe bar,and means for attaching said bar to a fence post; of a pulley on theslide, a chain led over said pulley, and grips at opposite ends of saidchain for attachment to the fence wire.

2. In a fence wire stretcher, the combination with a bar, a slidemovably'mounted thereon, means for causing its progression along thebar,and means at opposite ends'of said bar for sele'ctive'use in attachingit to a fence post; of a pulley mounted on said slide, a chain passingaround said pulley and with one stretch adapted to be led past a fencepost, and grips at the extremities of said chain for attachment to thefence Wire 1 at two points, as described.

3; In a fence 'wire stretcher, the combina tion with a notchedbar, andmeans at one end thereof for attaching it to a fixed ob- Copies 01 thispatent may be obtained for five cents each, by addressing Washington, D.0. v

ject; of tubular slide movably mounted on said bar, pins upstanding fromthe shde, a

lever pivotally mounted on one pin, a pawl carried by one end of thelever and adapted .to engage the notches of the bar, a pulley grip, anda hook on the other grip adapted to be engaged; with said large link,for the purpose set forth.

5. In a fence Wire stretcher, the combination of a bar, a slide movablymounted thereon, means for causing its progresslon along the bar, andmeans for attaching it to a fence post, of a pulley mounted on saidslide, a chain passing around said pulley and with one stretch adaptedto be led past a fence post, and grips 'at' the extremities'of saidchain for attachment to a fence wire at two points,-as described' 7 a 16. In a fence wire stretcher, the combination with a bar, andmeans forattaching it to a fixed object, of a slide movably mounted on said bar,pins upstanding from the slide, of a lever pivotally mounted on one pin,means carried by said lever to engage the bar and move the slide alongthe bar as the lever is swung, a pulley mounted on the pin, a linkconnecting the upper ends of said pins, a chain passing around saidpulley, and means on the pins for engaging the fence wire.

In testimony whereof I aliix my signature in presence of two witnesses.
